Be sure to transport the vehicle with all four wheels raised off the ground. If the vehicle is
towed with the tires contacting the ground, the drivetrain and related parts may be damaged,an accident may occur due to a change in
direction of the vehicle or electricity generated by the operation of the motor may cause a fireto occur depending on the nature of the dam-
age or malfunction.
